though completely apterous. C. tepperi (Shaw, I.e., p. 157) was the first of 

 these species to be described; the present paper includes two more, spryi and 

 feriarum, and an undescribed species in my collection from Daly River, N. Terri- 

 torj^, makes a fourth. 



Genus Zoxioploca Stal. 



ZoxiOPLOCA DisoNi^ n.sp. 



Castaneous above, rufo-testaceous beneath. Head with the vertex rufo- 

 castaneous; a large rufo-castaneous macula occupying the greater part of the 

 frons, but paling to testaceous around the antennary fossae, on the margin of the 

 clypeus and on the lateral portions of the head; eyes black; antennae rufo- 

 testaceous. Thoracic tergites rugose; pronotum with the lateral margins much 

 thickened, meso- and metanotum with the lateral margins thickened, postero- 

 lateral angles somewhat produced backwards, no flying organs. Abdominal ter- 

 gites smooth, nitid, their posterior margins furnished with a row of small tubercles ; 

 tergite 5 with the postero-lateral angles not, or but slightly produced backwards, 

 tergites G and 7 with the same well-produced, lateral margins entire. Supra- 

 anal lamina of the <S (Text-fig. 7) rufo-testaceous, subquadrate, widely emarginate, 

 eiliate, lateral margins concave, ending posteriorly in a spine directed backwards 

 and outwards; cerci slightly incurved, blunt at the apex, extending to about the 

 length of the lamina; of the 2 nan'ower at the apex, with three or four blunt 

 spines at each side, lateral margins slightly erenulate. Subgenital lamina of d' 

 (Text-fig. 7) backwardly produced, lateral margins concave, terminating in two 

 divergent pointed processes; styles long, acuminate, laterally inserted. Legs rufo- 

 testaceous; coxal borders pale; posterior tibiae in the ? furnished on the whole 

 length of their inner borders with a closely-set brush of fine hairs; posterior 

 metatarsus of about the leng-th of the remaining tarsal segments combined, not 

 spined beneath, pulvillus apical, remaining pulvilli occupying the whole seg- 

 ment, arolia large. Length, 3 26.5 mm., 5 32.0 mm.

Notes. — The material on which this species is founded came to me from my 

 friend Mr. F. P. Spry. About a year ago he sent me a 5 of what appeared to 

 be a new Zonioploca Stal taken by Mr. J. C. Dixon in the Mallee district of Vic- 

 toria, and later, in response to enquiries, a larval S from the same locality and 

 captor, and a c? and a 2 labelled as from Central and South Australia respec- 

 tively, from an old collection of Mr. C. French, lately Govt. Entomologist of 

 Victoria. These latter have been selected as the types, and the Mallee specimens, 

 though so far structurally indisting-uishable, are of a darker colour, less robust, 

 and less rugose; until more material is found no good purpose will be served 

 by regarding them as more than a dark variety. The species differs from the 

 rest of the genus in some particulars such as the postero-lateral angles of the 5th 

 abdominal tergite being scarcely produced, the smoother dorsum, the thickened 

 lateral margins of the meso- and metanotum, and the form of the subgenital 

 lamina of the <S; but the 6th and 7th tergites are well produced, the pronotum 

 has a thickened margin, and the tarsal structure is that of Zonioploca Stal. Mr. 

 Dixon is a keen naturalist who has added considerably to our knowledge of the 

 Mallee fauna, and as some slight acknowledgment of this it is proposed that this 

 species should be named after him.
